Kawasaki SX-R 1500, GP1R & F16 ECU Tune - Mail-In Reflash
Kawasaki SX-R 1500, GP1R & F16 ECU Tuning by Cabrera Motorsports
The Kawasaki 1500 four-stroke is the engine of modern stand-up racing, whether it sits in a factory SX-R 1500 hull or a Fast PowerSports GP1R or F16 race hull. The stock calibration holds it back with speed limiters, throttle delays, and conservative fueling. A CMS custom tune removes those limits and is built around your exact engine, stock or modified, and your fuel. This is our race class. We build, tune, and race these skis ourselves.

➕ What a CMS Kawasaki 1500 Tune Does
- Factory speed limiter removed. Ride to your ski's true top speed instead of the factory cap.
- Sharper throttle response. Factory throttle delays and torque limiters are eliminated for instant response, exactly what you want on a stand-up.
- Optimized fueling and RPM limits. Calibrated for your fuel and your setup, from stock to cams, intake, and exhaust.
We ride and race these exact setups on our own builds. We race what we sell!
🏄 Hulls We Tune
Kawasaki SX-R 1500 (2017+)
The factory stand-up. Stock or modified, from a rec-rider 93 octane tune to a full race calibration, the tune is built for your parts list.
Fast PowerSports GP1R & F16
Race hulls built around the Kawasaki 1500 engine and electronics. As an authorized Fast PowerSports retailer, we tune the same ECU in these hulls, and we calibrate for the modified engines that usually go in them.
The same 1500 engine also powers the STX-15F. Select the SX-R tile in the configurator and note your hull in the additional information box.
🔧 Stock or Modified
The configurator asks whether your engine is stock or has internal modifications, with a box for the rest: free-flow exhaust, aftermarket intake, cams, and anything else on the ski. The calibration is built for what's actually in your hull, not a generic file.
⛽ Fuel Options
93 octane pump gas is the right tune for most riders. For race builds, we also calibrate for AVGAS, VP MS109, and Ignite E85. Select your fuel in the configurator.

❓ FAQs
Can I use the RTD on my Kawasaki 1500?
No. The Kawasaki 1500 ECU is mail-in only. Ship it to us and we flash it on the bench.
Do you tune modified engines?
Yes. That's most of what we do on this platform. Tell us your modifications in the configurator and the calibration is built for them.
How much faster will my ski be?
Real-world results depend on your ski's condition, load, and water conditions, so we don't promise a specific number. We calibrate each tune to get the most out of your ski safely on your chosen fuel.
Can I go back to stock?
Yes. Your stock calibration is backed up and you can request a return to stock.
Is my warranty affected?
ECU modifications can affect factory warranty coverage. Most of our customers accept the trade for the performance.
